Im sure the shifter will be fine once I get another shot at it. I just thought with the wrong instructions and it not fitting together quickly that it might be the wrong one. The real problem is my DT header which is a piece of shit, made from a piece of shit company that has not done anything yet to help me

Found out what I was doing worng. I wasn't forcing the shifter down into the extension hard enough. Got it all installed now and WOW! I can't believe the difference. Night and day. Possibly the best mod I have done yet. Shorter, smoother and alll around a better feel.
